A
Supplier of Last Resort (SOLR) is an entity that provides Last Resort Supply
to contestable customers who suddenly find themselves without a Retail Electricity
Supplier (RES).

Last
Resort Supply is regulated by the Energy Regulatory Commission (ERC) as a back-up
supply for contestable customers upon discovery of any of the Last Resort Supply
Event:

The RES OR Local RES has ceased to operate;

The RES' license has been revoked by ERC;

The arrangements for DWS between the RES and the DU have been terminated;

The RES or Local RES is no longer permitted to trade electric energy through the WESM;

The RES or Local RES has given notice to the ERC that it will no longer provide supply services; or

Any other analoguous event which the ERC may deem as a Last Resort Supply Event.

The
SOLR is not a ‘generator of last resort’ in times of power shortage
or black out. Such events are managed by the System Operator and the DU, and
will be guided by the procedures in the WESM
Rules (Amendments),
the Grid
Code and the Distribution
Code.
